'Head' in the Bible

But if anyone goes out the doors of your house into the street, his blood shall be on his own head [that is, his own responsibility], and we shall be blameless and free [from our oath]; however, if a hand is laid on anyone who is with you in the house, his blood shall be on our head.

and with him ten leaders, one leader from each father’s household from each of the tribes of Israel; and each one was the head of his father’s household among the thousands of Israel.
